There is no published list of acceptable publications.
Most employers, based on their normal recruiting efforts, will be able to readily identify those newspapers (or journals for certain professional positions) that are most likely to bring responses from able, willing, qualified, and available U.S. workers.
The employer must be able to document that the newspaper and/or journal chosen is the most appropriate to the occupation and the workers likely to apply for the job opportunity.
Generally, the newspaper advertisements must be placed on two different Sundays at least 30 days, but no more than 180 days, prior to filing the application. The Sundays may be consecutive.
However, if the job opportunity is located in a rural area that does not have a newspaper that publishes a Sunday edition, the employer may use the newspaper edition with the widest circulation.
This exception applies to rural newspapers only. If a suburban newspaper has no Sunday edition, the employer must publish the Sunday advertisement in the most appropriate city newspaper that serves the suburban area.
For journals, there is no specific edition requirement, however, the advertisement must be placed at least 30 days, but no more than 180 days, prior to filing the application.
The H1b visa program permits employers to provisionally employ foreign workers in the United States on a nonimmigrant basis in jobs such as special professions or as models of eminent merit and aptitude. A specialty profession requires the hypothetical and practical application of an entity with specific knowledge and a bachelors degree or the comparable in the specific specialty. H1b visa requirements depend on a sponsor (a company in the US), who needs to submit a Labor Condition Application. H1b visa status depends on DOL and the USCIS (Immigration and Naturalization Service) decisions. PERM foreign labor applicaton and certification is obtained via US Department of Labor.
